I owned the Integra for several years. The main thing lacking with the SN-A solo sounds is a realistic vibrato. If a vibrato is not sampled, but created by modeling parameters, it just never sounds realistic. I especially disliked the vibrato of solo strings.
Some of the underlying „samples“ the SN-A sounds are derived from are also not too convincing. Saxophones are really poor.
Take the trumpets. The physical modeling provides some very nice effects such as glissandi and legato. But on the other hand, the vibrato sucks. All in all, I often preferred a Yamaha Motif or Ketron trumpet with a nice vibrato over the SN-A trumpet that never sounded inspiring when playing long notes.
I, too, disliked some of the vibrato's, especially on certain instruments, like, reeds and brass. On the plus side, the Integra-7 has the SRX boards, including the SRX-10 (brass), and the SRX-06 (orchestral - strings, woodwinds and brass), which I find to be more realistic.
So, how do you compare the MODX's strings to the Integra's SN and SRX strings? How about DSF's strings? Again, they say the strings on the MODX are better than the Motif's, and I would agree, but to my ears, they still are not extremely convincing, especially the large ensembles.
Thanks for you comments.
